Cause of death uncertain for Olympia woman found on Division Street, coroner’s office says

An autopsy on a woman who died after a street sweeper found her unconscious in west Olympia did not determine her cause of death, according to the Thurston County Coroner’s Office.

Yvonne McDonald, 56, was found unconscious the morning of Aug. 7 on the 900 block of Division Street Northwest a few blocks from her apartment, according to Olympia police. She was taken to Providence St. Peter Hospital, where she died that evening.

Police had been investigating the case as an unattended death as they awaited the coroner’s office determination of how she died.

Thurston County Coroner Gary Warnock said Friday’s autopsy did not determine cause of death and that officials must now wait for results from a toxicology report from the Washington State Patrol lab, which could take several months.

Police have asked anyone with information in the case to call 360-753-8300.
